Abstract
An organic EL device includes an organic EL element that includes an anode having a reflective face, a cathode having a semi-transmissive reflective layer, and a functional layer, which is pinched between the anode and the cathode and includes at least an organic light emitting layer, and configures a color pixel that implements light emission corresponding to at least a red color. The color pixel configured by the organic EL element forms an optical resonator between the reflective face of the anode and the semi-transmissive reflective layer of the cathode. The color pixel corresponding to the red color has a film thickness profile of the functional layer in a convex shape in which a center portion is relatively thick, and a periphery portion is relatively thin or a concave shape in which the center portion is relatively thin, and the periphery portion is relatively thick.
